Additionally, the virtual transaction card may be transmitted to a delegate mobile device. Other mobile usage constraints, such as location bounded policies and type of transaction policies may also be used.

BACKGROUND

1. Technical Field

Embodiments generally relate to authorizing transactions. Moreparticularly, embodiments relate to the use of virtual transaction cardsto authorize transactions in mobile environments.

2. Discussion

Conventionally, in order to authorize another individual to maketransactions with respect to a credit card account, either the accountholder's card may be given to the other individual or the otherindividual may be issued a credit card with his or her name on it. Suchan approach may present challenges with regard to controlling spending,particularly when the other individual is a teenager, adolescent, etc.While an alternative approach may be to purchase a gift card for theother individual, certain challenges remain. For example, purchasing agift card (e.g., via third party or point of sale terminal) may involvea separate transaction, which may be inconvenient and time consuming forthe account holder. Moreover, traditional gift cards may be limited tocontrolling the maximum amount spent and/or particular retailer.

DETAILED DESCRIPTION

Turning now to FIG. 1, an architecture 10 to authorize transactions isshown. Generally, an account holder/subscriber 12 may have a creditand/or debit card account that enables the subscriber 12 to makepurchases at retail locations, on web sites, etc., without the need forcash in order to complete the transactions. In the illustrated example,the subscriber 12 may use one or more devices 14 to issue a virtualtransaction card to a mobile device 18 associated with a delegate 16,wherein the delegate 16 may use the virtual transaction card to make oneor more purchases at a point of sale terminal 20, web site, or othercommercial transaction location. In one example, the devices 14 include“mobile wallet” functionality that enables the subscriber 12 to conductfinancial transactions in a secure environment on the devices 14. Ofparticular note is that the subscriber 12 may generate the virtualtransaction card without involving third parties or point of saleterminals. For example, the illustrated devices 14 execute secure logicthat is able to set the value of the virtual transaction card as well asone or more mobile usage constraints, without conducting a separatetransaction, wherein the virtual transaction card may be delivered tothe mobile device 18 via a near field communications link 22 or otherconnection such as a network interface link. The card value may be arelatively small value (e.g., in relation to the amount of availablecredit in the account), which may enable the subscriber 12 to tightlycontrol the purchases made by the delegate 16.

Moreover, the mobile usage constraints may provide even greater controlover the purchases of the delegate 16, relative to conventionalsolutions. For example, the subscriber 12 may set a time bounded policyfor the virtual transaction card, wherein if the time bounded policy isnot satisfied, the card is deemed invalid at the time of the attemptedpurchase. Thus, if the subscriber 12 stipulates that the virtualtransaction card must be used within the next twenty-four hours, if thedelegate 16 attempts to use the card to make a purchase after thetwenty-four hour period has expired, the attempted transaction may bedenied at, for example, the point of sale terminal 20.

Additionally, the subscriber 12 may set a location bounded policy forthe virtual transaction card, wherein if the location bounded policy isnot satisfied, the card is invalid. Thus, if the subscriber 12stipulates that the virtual transaction card must be used within aparticular geographic radius, at a particular store, or on a particularweb site, if the delegate 16 attempts to make a purchase at a differentlocation or web site, the attempted transaction may be denied at, forexample, the point of sale terminal 20. The location bounded policy mayalso indicate that a particular store or web site is prohibited, whereinif the delegate 16 attempts to make a purchase at the prohibited storeor web site, the attempted transaction may be denied. Other mobile usageconstraints such as transaction type policies (e.g., genre, type ofproduct or service), number of transactions, and so forth, may also beused.

Indeed, the mobile usage constraints could also define more advancedpolicies for the delegate 16 such as 1) setting “X” number of additionalpre-paid cards that may be generated through the delegate's virtualtransaction card (e.g., additional card policy), 2) eliminating userID/authentication checks for such pre-paid cards while linking theidentification information of the delegate's virtual transaction card tothe subscriber's card (e.g., authentication policy), 3) digitallylinking pre-approved information (e.g., subscriber's last four socialsecurity number digits) to the delegate's mobile wallet, wherein thelinked information can be associated with the delegate's virtualtransaction card when needed, 4) preventing the generation of newvirtual transaction cards to the delegate until outstanding balanceshave been paid, and so forth.

In order to facilitate the management of the virtual transaction cards,parameters of the generated virtual transaction cards may be transmittedto a rule management module 26 in a cloud computing infrastructure 24,wherein the management module may be responsible for aggregating andmaintaining all rules associated with a specific account, and reporting(e.g., via emit, text or other mode of communication) the activities ofthe delegate 16 to the subscriber 12. Of particular note, however, isthat the devices 14 may generate the virtual transaction cards anddistribute them to their respective delegates without conducting afinancial transaction, authorization, etc., with regard to themanagement module 26 or other payment system component. Rather, theillustrated management module 26 merely provides the virtual cardinformation (e.g., card values, mobile usage constraints) needed toconduct real-time approval of purchase requests at product and/orservice providers such as, for example, the point of sate terminal 20.

In this regard, the point of sale terminal 20, may also include a rulemodule (not shown) that receives card information entered by the userand verifies the satisfaction of the appropriate policies/constraintswith the management module 26 in real-time. The point of sale terminal20 may also send transaction notifications to the subscriber 12.Alternatively, the mobile device 18 of the delegate 16 may be configuredto run an account management application that provides transactionnotifications to the subscriber 12.

FIG. 2 shows a method 28 of authorizing transactions. The method 28 maybe implemented as a set of executable logic instructions stored in atleast one machine- or computer-readable storage medium such as randomaccess memory (RAM), read only memory (ROM), programmable ROM (PROM),flash memory, firmware, microcode, etc., in configurable logic such as,for example, programmable logic arrays (PLAs), field programmable gatearrays (FPGAs), complex programmable logic devices (CPLDs), infixed-functionality hardware using circuit technology such as, forexample, application specific integrated circuit (ASIC), complementarymetal oxide semiconductor (CMOS) or transistor-transistor logic (TTL)technology, or any combination thereof. For example, computer programcode to carry out operations shown in the method 28 may be written inany combination of one or more programming languages, including anobject oriented programming language such as C++ or the like andconventional procedural programming languages, such as the “C”programming language or similar programming languages. Moreover, variousaspects of the method 28 could be implemented as embedded logic of aprocessor using any of the aforementioned circuit technologies.

Illustrated processing block 30 provides for receiving user input via asubscriber mobile device having a mobile wallet capability, whereinblock 32 may involve identifying a card value and one or more mobileusage constraints based on the user input. Thus, the user input may beused to set policies for an expiration time, a location, a card value,and so forth, in the illustrated example. A virtual transaction card maybe generated based on the card value and mobile usage constraints, andsent to a delegate mobile device at block 34. In one example, a secureprocessing element on a subscriber mobile device is used to generate andsend the virtual transaction card, wherein the card may be transmittedvia a near field communications (NFC) module, network interface, and soforth. Additionally, illustrated block 36 transmits the virtual totransaction card parameters to a payment network (e.g., Euro,Mastercard, Visa/EMV) component such as, for example, the rulemanagement module 26 (FIG. 1), already discussed. Block 36 may involveretrieving encryption information (e.g., private keys, digitalsignatures) from a secure storage element of a subscriber mobile device,and using the encryption information to transmit the card value and themobile usage constraints to the payment network component.

The virtual transaction card parameters may be received on the delegatemobile device at block 38, wherein illustrated block 40 detects one ormore purchase attempts. The purchase(s) may be verified against the cardparameters at block 42 by, for example, transmitting an authorizationrequest to a cloud based rule management module such as the rulemanagement module 26 (FIG. 1), already discussed. Additionally, anyappropriate rule based actions (e.g., notifications, approvals, denials)may be taken.

FIG. 3 shows a computing platform/system 46 that may be part of a mobiledevice having computing functionality (e.g., personal digitalassistant/PDA, laptop, desktop, smart tablet), communicationsfunctionality (e.g., wireless smart phone), imaging functionality, mediaplaying functionality (e.g., smart television/TV), or any combinationthereof (e.g., mobile Internet device/MID). In the illustrated example,the system 46 includes a central processing unit (CPU) 48, an integratedmemory controller (IMC) 50, a platform controller hub (PCH) 52, systemmemory 54, a network controller (e.g., network interface card) 56,non-volatile memory (NVM) 58, and one or more user interface (UI)devices 60. The CPU 48, which may include a core region with one orseveral processor cores 62, could alternatively communicate with anoff-chip variation of the IMC 50, also known as a Northbridge, via afront side bus or a point-to-point fabric that interconnects each of thecomponents in the system 46. In particular, the UI devices 60 may becapable of enabling a user to interact with and perceive the interfacefrom the system 46.

The illustrated PCH 52, sometimes referred to as a Southbridge or SouthComplex of a chipset, functions as a host controller and communicateswith the network controller 56, which could provide off-platformcommunication functionality for a wide variety of purposes such as, forexample, cellular telephone (e.g., W-CDMA (UMTS), CDMA2000(IS-856/IS-2000), etc.), WiFi (e.g., IEEE 802.11, 1999 Edition, LAN/MANWireless LANS), Bluetooth (e.g., IEEE 802.15.1-2005, Wireless PersonalArea Networks), WiMax (e.g., IEEE 802.16-2004, LAN/MAN BroadbandWireless LANS), Global Positioning System (GPS), spread spectrum (e.g.,900 MHz), and other radio frequency (RF) telephony purposes. Theillustrated system 46 also includes a near field communications module64, which may further coordinate with the PCH 52 to facilitateoff-platform communications using, for example, radio frequencyidentifier (RFID) technology. The PCH 52 may also include one or morewireless hardware circuit blocks to support such functionality.

The NVM 58 may include one or more hard disk drive (HDD) devices, solidstate disk (SSD) NAND chips, etc., and may be used to provide highcapacity data storage and/or a significant amount of parallelism. Theremay also be solutions that include NAND controllers implemented asseparate ASIC controllers being connected to the PCH 52 on standardbuses such as a Serial ATA (SATA, e.g., SATA Rev. 3.0 Specification, May27, 2009, SATA International Organization/SATA-IO) bus, or a PCI ExpressGraphics (PEG, e.g., Peripheral Components Interconnect/PCI Express x16Graphics 150W-ATX Specification 1.0, PCI Special Interest Group) bus.The NVM 58 could also be used as a USB (Universal Serial Bus, e.g., USBSpecification 3.0, USB Implementers Forum) flash storage device.

The illustrated system 46 also includes a secure processing element 66that runs an embedded operating system (OS) such as Java CardOpenPlatform (JCOPO) or SmartCafe OS from NXP Semiconductors, Eindhoven,The Netherlands. In one example, the embedded OS can be run securelywithout involving any host OS running on the CPU 48. The illustratedsecure processing element 66 includes a card generation module 68configured to generate a virtual transaction card based on a card valueand one or more mobile usage constraints including a time boundedpolicy, wherein the virtual transaction card is to be invalid if thetime bounded policy is not satisfied. Other policies such as a locationbounded policy and transaction type policy may also be used. Ofparticular note is that the virtual transaction card may be generatedwithout involving a third party or point of sale terminal.

The secure processing element 66 may also include a card distributionmodule 70 configured to transmit the virtual transaction card to adelegate mobile device. The virtual transaction card may be transmittedto the delegate mobile device via, for example, the near fieldcommunications module 64, the network controller 56, and so forth. Theillustrated secure processing element 66 also includes a networkidentification module 72 configured to transmit the card value and theone or more mobile usage constraints to a payment network component. Inone example, the network identification module 72 retrieves encryptioninformation 74 from a secure storage element 76, and uses the encryptioninformation 74 and the network controller 56 to communicate with thepayment network component. The card value and one or more mobile usageconstraints may be obtained from an account holder/subscriber 12 such asthe subscriber 12 (FIG. 1) via the UI devices 60.

Thus, techniques described herein may enable credit/debit card owners toset spending limits for delegate card users, limit where the card can beused (e.g., by genre, brick and mortar store, location, web site, etc.),limit the number of transactions the delegate can make, monitor spendingactivity, approve individual expenses in real-time through a paymentnotification and approval process, receive information on how thedelegate is attempting to use the owner's card, and so forth. Thetechnology may be effectively used by either issuer banks or by EMV toenable users to generate small value transactions cards, pre-paid cards,or credit cards. In addition, the transaction card generatingapplication may run in a secure element via a mobile wallet option. Themobile wallet option may also send messages to a payment network (suchas EMV) and/or to an issuer bank either as encrypted SMS (shortmessaging service, text) message or an IP (Internet Protocol) connectionmessage.
